Neurological Presentation of Invasive Mucormycosis.

An elderly female presented to the emergency department with a right-sided facial droop and headache for two weeks. Investigations revealed poorly controlled diabetes, and the patient was found to be in diabetic ketoacidosis. Maxillofacial computed tomography (CT) demonstrated right postseptal cellulitis with concern for acute invasive fungal sinusitis. The patient was taken to the operating room for orbital surgical exploration and antrostomy. Surgical pathology revealed broad hyphae consistent with Rhizomucor species, and the patient was diagnosed with mucormycosis. Because the patient was not clinically improving, further imaging was obtained, which showed a large right retroantral phlegmon extending into the cranial fossa and right cavernous sinus, and the patient subsequently underwent surgical debridement. The following postoperative day, the patient was stroke-alerted due to altered mental status and inability to follow commands. She was found to have a small embolic infarct. Due to the poor prognosis of the patient, she was discharged with hospice. Mucormycosis is more commonly found in immunocompromised patients, such as those with uncontrolled diabetes mellitus but very rarely does it involve the cranium. This disease process is very important to recognize early due to high morbidity and mortality rates and devastating outcomes.

Accelerated right heart failure due to lung resection in the setting of chronic respiratory failure.

A 68-year-old woman with a past medical history of chronic obstructive pulmonary disease and squamous cell carcinoma of the lung with recent right upper and middle lobectomy was admitted for dyspnea and volume overload. She was diagnosed with right-sided heart failure (RHF) through clinical, laboratory, and echocardiographic means. In the setting of chronic respiratory failure, the recent right lung lobectomy was deemed to be the inciting factor of the RHF. The mechanism by which RHF occurs in this situation is multifactorial, and it is essential to undergo pre-operative risk stratification and post-operative monitoring to avoid emergent events. .

Clavicular Metastasis as an Initial Presentation of Papillary Thyroid Cancer.

OBJECTIVE: We present the case of a 44-year-old man with a large neck mass to highlight the unique presentation of papillary thyroid carcinoma (PTC) metastatic to the clavicle. METHODS: We reviewed the medical record for a detailed history and physical examination findings. Our radiology colleagues examined the diagnostic imaging studies performed. The pathology team reviewed the neck mass biopsy and the confirmatory surgical pathology after total resection of the mass. RESULTS: A 44-year-old man presented with an enlarging neck mass. Initial X-rays revealed a large soft tissue density mass that extended to the midline of the right clavicle. A neck ultrasound established a 5.4 × 3.6 cm mass with increased vascularity and calcification extending from the thyroid. A CT scan noted the extension of the mass into the adjacent sternoclavicular junction with osteolysis of the middle third of the clavicle and the superior aspect of the sternal body. Fine-needle aspiration revealed a thyroid neoplasm with follicular features and positive immunostaining consistent with thyroid carcinoma. The patient underwent a composite resection of the tumor, including a segmental osteotomy of approximately two-thirds of the medial clavicle. The pathology report confirmed PTC with extrathyroidal extension and clavicle involvement (staged pT4a pN0), with further genomic findings showing positive KRAS mutation. CONCLUSION: Clavicular metastasis from differentiated thyroid cancer is rare. While the prognosis is generally favorable, various factors, including age greater than 45 years, poor differentiation, follicular thyroid carcinoma, Hurthle cell variant, and extrapulmonary metastasis, have typically been associated with poorer cancer-specific survival.

Healed Varicella Pneumonia: A Case of Diffuse Pulmonary Microcalcifications.

Varicella pneumonia is a potentially fatal complication of the Varicella-zoster virus (VZV), which causes the well-known chickenpox disease of childhood. Identifying this type of pneumonia by characteristic features is important for radiologists and radiology residents. Typical manifestations of active Varicella pneumonia include diffuse pulmonary nodules, which may mimic other diseases. Healed Varicella pneumonia can present as diffuse, calcified pulmonary micronodules. We describe a case of healed Varicella pneumonia in a patient with a history of remote VZV infection.

Gynecological Care and Contraception Considerations in Women with Cerebral Palsy.

The purpose of this literature review was to further explore gynecological care and contraceptive use in women with cerebral palsy. We address barriers to pelvic examinations for cervical cancer screenings and current contraceptive methods in severely debilitated patients with cerebral palsy.

A case of West Nile virus encephalitis accompanied by diabetic ketoacidosis and rhabdomyolysis.

INTRODUCTION: We present here a case of West Nile Virus (WNV) encephalitis that initially presented with diabetic ketoacidosis and rhabdomyolysis. CASE PRESENTATION: A 35-year-old male with no past medical history presented to the emergency department complaining of polydipsia, generalized weakness, lightheadedness, and visual disturbances of one week duration. He was found to be in diabetic ketoacidosis. His hemoglobin A1c was 11%. The patient was appropriately treated for diabetic ketoacidosis and it resolved on hospital day 1. On hospital day 2, the patient developed a fever of 101.6 °F and his mental status became severely altered. He developed auditory and visual hallucinations. IgM and IgG antibodies to West Nile Virus were positive in the cerebral spinal fluid (CSF). The patient's creatine kinase level rose to 118,400 U/L during his hospitalization and eventually returned to baseline. The patient made a full recovery with no residual neurologic deficits after an 11 day hospital course. DISCUSSION: In this patient, neuroinvasive WNV was confirmed with positive CSF IgM. The patient's newly diagnosed diabetes likely contributed to his susceptibility to neuroinvasive disease. Furthermore, WNV encephalitis in a background of DKA has not been previously described in the literature and this case demonstrates WNV neuroinvasive disease should be in the differential diagnosis for patients presenting with unexplained neurological symptoms. CONCLUSION: Diagnosis of neuroinvasive WNV is imperative to stop unnecessary therapies, limit further diagnostic evaluation, help predict patient outcomes, direct public health prevention measures, and further provide investigations into the clinical conditions that define the spectrum of WNV disease.

Role of handedness on forearm skin tissue dielectric constant (TDC) in relation to detection of early-stage breast cancer-related lymphedema.

skin tissue dielectric constant (TDC) measurements help assess local skin water to detect incipient early-stage lymphedema subsequent to breast cancer treatment-related lymphedema. However, presurgery measurements are not always obtained and assessments for evolving lymphedema are only made after surgery. Thus, subsequent TDC assessments may be biased in an unknown way dependent on a patient's handedness in relation to the at-risk arm. We investigated this issue by comparing TDC values in dominant and non-dominant volar forearms of 31 left-handed women and 31 right-handed women (age range 24-84 years). Body fat and water percentages were assessed by bioimpedance at 50 KHz. Results showed that TDC values of dominant versus non-dominant arms did not significantly differ for left-handers or for right-handers. There was also no statistically significant difference in absolute TDC values between left- and right-handers or a statistically significant difference in dominant-to-non-dominant arm ratios between left- and right-handers. For the composite data set (N = 62), TDC values for dominant and non-dominant arms were, respectively, 30·0 ± 4·6 and 29·6 ± 4·2 and the dominant-to-non-dominant arm TDC ratio for combined left- and right-handers was 1·015 ± 0·075. These results suggest that handedness is not a major factor when assessing lymphedema status in women who have previously been treated for breast cancer but for whom pretreatment TDCvalues have not been obtained. Moreover, these results suggest that threshold ratios of incipient subclinical unilateral lymphedema based on interarm TDC ratios apply independent of a patient's handedness for the site and tissue depths herein measured.

Age and Hydration dependence of jowl and forearm skin firmness in young and mature women.

BACKGROUND: Quantitative assessment of possible linkages between skin's firmness and water content is useful for cosmetic and clinical purposes and to better understand features of advancing age. OBJECTIVES: Our goals were to characterize age-related differential features in skin firmness in women and determine the relationship between skin firmness and indices of skin water. METHODS: Skin firmness was quantified using handheld devices that measure the force to indent skin 0.3 and 1.3 mm (F0.3 and F1.3). Skin hydration was quantified using handheld devices that measured tissue dielectric constant (TDC) at 300 MHz to skin depths of 0.5 and 2.0-2.5 mm. All parameters were measured bilaterally in the jowl area and volar forearm of 60 women grouped by age <45 years (YOUNG) and ≥45 years old (MATURE). RESULTS: All measured parameters were bilaterally symmetrical at jowl and forearm. Forearm and jowl indentation forces were greater in YOUNG with statistically significant declines with advancing age with regression relations most evident at shallower indentation depths (P < .001). Quantitative relations for arm and jowl were F0.3 = 0.256 × AGE + 32.7 mN and F0.3 = -0.07 × AGE + 17.7 mN. Firmness was related to TDC values only when indentation force and TDC were assessed on the arm at the shallowest skin depths, as weakly related to firmness and was observed to change with age only when measured to a depth of 0.5 mm represented by TDC5 = 0.096 × AGE + 32.7. CONCLUSIONS: Experimental finding show clear differences in skin firmness between age-groups with skin hydration playing a minor role. Possible explanations and suggestions for further studies are provided.
